Networking RequirementsAs shown in Figure 1, Ethernet 2/0/1 of the Router is connected to the uplink interface of SwitchA.On SwitchA, the downlink interface Ethernet 2/0/1 is added to VLAN 10 and the downlink interface Ethernet 2/0/2 is added to VLAN 20.PC1 in VLAN 10 and PC2 in VLAN 20 need to communicate with each other

As shown in Figure 1, the S5700 Huawei is deployed at the access layer of a campus network toprovide high performance, multi-service, and highly reliable enterprise network.Figure 1 Position of the S5700 on a Large-scale enterprise campus networkThe S5700 provides various terminal security management features, and supports functions such as PoE, voice VLAN, and QoS. The S5700 can be used for desktop access and provides GE access.

The S5700 provides various security features including ARP security, IP security, IP source guard, and user access control policies such as NAC and ACLs, to control access of user terminals.

The S5700 provides Easy-Operation and USB-based deployment, which facilitates deployment and management.

Example for configuring local attack defense for Huawei routers to all versions.

Networking RequirementsAs shown in Figure 1, users on different LANs access the Internet through Router A. To locate attacks on Router A, attack source tracing needs to be configured to trace the attack source. The following situations occur:

ContextThe fan speed affects the device temperature. When the device temperature is high, increase the fan speed to lower the device temperature. When the device temperature is low, reduce the fan speed to save energy.

NOTEBy default, fans run in automatic mode. In this mode, the system adjusts the fan speed when detecting that the board temperature increases or decreases. The automatic mode reduces noises and saves energy without affecting system running. Therefore, exercise caution when setting the fan speed.The AR151&200 series does not support this function.
